The self-consistent calculation of exchange enhanced odd integer quantized Hall plateaus within Thomas-Fermi-Dirac approximation
(Elsevier Science Bv, 2010)
We study the emergent role of many-body effects on a two-dimensional electron gas (2DEG) within the Thomas-Fermi-Dirac-Poisson approximation, including both the exchange and correlation interactions in the presence of a ...
Microscopic theory of the activated behavior of the quantized Hall effect
(Elsevier Science Bv, 2010)
The thermally activated behavior of the gate defined narrow Hall bars is studied by analyzing the existence of the incompressible strips within a Hartree-type approximation. We perform self-consistent calculations considering ...
Spatial distribution of the incompressible strips at AB interferometer
(Elsevier Science Bv, 2010)
In this work, the edge physics of an Aharonov-Bohm interferometer (ABI) defined on a two dimensional electron gas, subject to strong perpendicular magnetic field B, is investigated. We solve the three dimensional Poisson ...
The current polarization rectification of the integer quantized Hall effect
(Elsevier Science Bv, 2010)
We report on our theoretical investigation considering the widths of quantized Hall plateaus (QHPs) depending on the density asymmetry induced by the large current within the out-of-linear response regime. We solve the ...
The effect of aging on the dark conductivity and noise in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)
Aging hydrogenated microcrystalline silicon in air is found to affect both the dark conductivity and the 1/f noise. For a sample with a crystalline volume fraction of 0.39, the conductivity decreased by three orders of ...
Investigation of light induced degradation in hydrogenated amorphous silicon-germanium alloy thin films using temperature dependent photoconductivity
(Wiley-V C H Verlag Gmbh, 2010)
Light induced degradation of undoped hydrogenated amorphous silicon-germanium (a-SiGe:H) alloys with different Ge contents has been investigated using intensity and temperature dependence of photoconductivity between 78K ...
The effects of native and light induced defects on optoelectronic properties of hydrogenated amorphous silicon-germanium (a-SiGe:H) alloy thin films
(Springer, 2010)
Effects of native and light induced defects states in hydrogenated amorphous silicon-germanium alloy thin films with different Ge concentrations have been investigated by using steady-state photoconductivity, dual beam ...
In vitro biocompatibility of plasma-aided surface-modified 316L stainless steel for intracoronary stents
(Iop Publishing Ltd, 2010)
316L-type stainless steel is a raw material mostly used for manufacturing metallic coronary stents. The purpose of this study was to examine the chemical, wettability, cytotoxic and haemocompatibility properties of 316L ...
Instability effects in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)
Instability effects on the dark conductivity (sigma(Dark)) and photoconductivity (sigma(photo)) of microcrystalline silicon films with different microstructures deposited on smooth and rough substrates, after exposure to ...
Phase states and thermomorphologic, thermotropic, and magnetomorphologic properties of lyotropic mesophases: Sodium lauryl sulphate-water-1-decanol liquid-crystalline system
(Amer Physical Soc, 2010)
Phase states in sodium lauryl sulphate-water-1-decanol lyotropic liquid-crystalline system have been investigated for different temperature ranges. The dependence of triangle phase diagram types, phase boundaries, and ...
